We had an awesome time exploring this huge beech in Mardley Heath Nature Reserve today. Apparently itโ€™s know as the monster tree due to how the roots have formed. It was wonderful. ๐Ÿ’—๐Ÿ’—๐Ÿ’—

Reviews Summary

Visitors rave about Mardley Heath as a beautiful, local woodland escape, perfect for quiet walks and dog adventures. Its transformation from a gravel quarry to a nature reserve is appreciated, with the unique 'monster tree' being a standout feature. While generally well-maintained, be prepared for muddy paths, especially after rain, and remember to take your litter with you.

"This has been walking distance from home for years and I never knew about it! I'm so glad to have discovered a lovely local place to go for a quiet walk and experience nature, especially during lockdown. Bring some shoes you don't mind getting muddy, or like me, come ill-prepared and just go for it anyway! An endless walk through the woods with some good bumps and ditches on way. What's more to love? ๐Ÿ˜"

Abdus Hosein

"Beautiful nature reserve with lots of paths to avoid people and social distance. Especially during autumn this is a blace to go. Have a wander through the birches and enjoy the colorful leaves, hunt for mushrooms and watch the Jays and squirrels squabble for acorns.

Don't be a terrible person and pick up your rubbish, don't litter :) the wildlife will thank you for it.
